PURPOSE: A camera module for improving distance control capacity of a VCM is provided to improve a current value applied in a coil of the VCM for improving the distance control capacity. CONSTITUTION: A camera module for improving distance control capacity of a VCM comprises the following: an image sensor(120) changing the light came through a lens module to an electric signal; a VCM(voice coil motor) operator(150) moving the lens module along to an optical axis by the increase of a magnetic flux of a coil connected with the coil in the VCM(voice coil motor) operator in parallel; and calculating a automatic focusing value from a brightness signal processed with an image processor(130).
